Speed/RPM (292's in particular)

[66Submarine]

Just curious, how hard do you/have you all run your trucks? Seems 55MPH/a little over 3,000RPM is real common, anyone here pushed/exceeded the limits? I'm particularly interested in hearing about 292 powered trucks. The hod rod/light truck guys seem to be afraid of them (292's), but I don't see any real reason they shouldn't hold up at high cruise RPM. Longer stroke, sure, but also much longer rods and 3/8" rod bolts. 250's, 350's, 454's, etc can all run 3,500RPM+ at cruise without letting go, I don't see why a 292 can't.

To clarify, I know that at 3,500RPM a 292 will be sucking fuel like air, and not really doing anything that well. I'm certainly not planning on cruising there, I just don't see why one can't. But, they are real hard to find, and I'm not wanting to do my own potentially destructive testing.
